Fatal error when creating new MqttClient

Trying to do an extremely basic demo… thing is created using other calls, and then…

const configBuilder = iotsdk.iot.AwsIotMqttConnectionConfigBuilder.new_mtls_builder(
  thing.certificatePem,
  thing.certificateKeyPair.PrivateKey
)
configBuilder.with_client_id(thing.thingName);
configBuilder.with_endpoint(thing.iotDataEndpoint)
const config = configBuilder.build();

const client = new iotsdk.mqtt.MqttClient();
const connection = client.new_connection(config);

Error:

/iotErrorProject/node_modules/aws-crt/dist/native/mqtt.js:61
        super(binding_1.default.mqtt_client_new(bootstrap.native_handle()));

I don’t see how this demo ever works, since bootstrap is not defined? https://github.com/aws/aws-iot-device-sdk-js-v2/blob/916eb692de7f6df9368324b34be71f67304c636c/samples/util/cli_args.js#L198

We recently updated the samples and CRT to not require the bootstrap, but we haven’t done a new release of the SDK yet so essentially the SDK samples are a little bit ahead of the pinned API. We’re planning to do a release soon with a lot of documentation improvements and updates so everything will be in sync then. In the meantime, just use the sample code from the latest release rather than what’s at the head of main.

No worries, thanks for your quick response!
